Luckily mobile A10-5750M (although this is 15h Richland, slightly newer than Trinity) found in G505S - has a functional IOMMU. H owever it wasn't working at proprietary UEFI - only with coreboot. Thank you very much for your explanation, and especially > let me just end with that's definitely not how I remember the discussions for > either of those two features note. > please refrain from posting baseless speculations on this mailing list Well, I just wanted someone to confirm or deny it. No harm from a "baseless speculation" if it is disproved at the next letter. Thanks to Marshall's letter, now I know that the return of IOMMU to 16h Puma together with the introduction of AMD PSP - is just a pure coincidence.
